Application June 13,1947,-Ser ia,lN0.754,3 9. j

This invention relates to a gas burner and vent pipe assembly, and more particularly to an assembly for use in garbage disposal units.

One of the prime objects of the invention is to design a gas burner assembly for disposal units, which cannot be smothered by covering with damp or wet refuse, and which will provide excellent heat radiation for heating, drying, and igniting the surrounding refuse and material.

Another object is to provide a shielded burner assembly that dries the surrounding garbage slowly, and then burns slowly, by limitation of the air supply to the combustion chamber, so that smoke and obnoxious odors are produced in limited volume and can be readily accommodated by the chimney, eliminating back-firing and preventing any objectionable odors escaping into the room in which the unit is housed.

A further object is to provide a highly efficient burner assembly that limits the heat radiated from the burning operation, and under fully automatic conditions, so that the refuse is evenly reduced to ashes without permitting any objectionable odors to escape to the exterior of the apparatus.

A further object still is to provide ashielded and vented burner assembly in which the flame cannot be put out by covering with garbage or refuse of any nature.

A further object still is to provide reflecting means associated with the burner assembly, to the end that it may be readily determined, visually, whether or not the burner flame is lighted.

A further object is to provide a vent leading from the burner to the smoke flue, eliminating any possibility of unburned gas collecting in the combustion chamber with danger of explosion when the burner is lighted, and/or during the burning and drying process.

With the above and other objects in View, the present invention consists in the combination and arrangement of parts, hereinafter more fully described, illustrated in the accompanying drawing, and more particularly pointed out in the appended claims, it being understood that changes may be made in the form, size, proportion, and minor details of construction, without departing from the spirit, or sacrificing any of the advantages of the invention.

In the drawing:

Fig. 1 is a side-elevational view of my garbage disposal unit, the side wall being broken away to show the burner assembly.

Fig. 2 is an enlarged, part-sectional view of the burner, vent pipe and reflector.

2 Claims. (01. 11018 5 Referring now more-specifically to the drawing in which I have shown the preferred embodiment of my invention, the numeral 5 indicates the casing of a refuse disposal unit; this is insulated as at 6, and the unit is formed with a combustion chamber 1, having a grate 8 disposed at the lower end thereof,'and a burner unit B is located approximately in the center of said combustion chamber.

An inner shell 9 surrounds the combustion chamberand'form's the'back wall of a smoke flue l0, and a horizontally disposed sleeve II is mounted on the inner shell back wall 9 extending to the casing 5. r v

A support pipe l2 ismounted in the sleeve II, the one outer end -being threaded as at I3 and accommodates acapv I4 which bottoms against the wall of the casing.

The opposite end of the support pipe I2 is also threaded and a conventional T-member [5 has threaded engagement therewith, a vertically disposed shield IB beingconnected to the upper end of the T, and a reflector R is mounted in the lower end as shown, said reflector being hingedly connected as at I! so thatit is normally disposed to prevent debris entering into the shield when refuse, etc. is placed in the combustion chamber.

A gas pipe 22 is connected to any suitable source of gas supply, and leads to the burner B which isv enclosed in the shield l6, and which is located,

- approximately in the center of the combustion chamber, so that the heat and flame is equally distributed.

When gas is fed to the burner B, the shield [6 will serve as a drier, and the gas flame will extend through the openings I8 in the shield to dry and ignite any refuse or garbage with which itcomes into contact.

In units of this nature, it is quite difficult, when the combustion chamber is filled, to determine if the gas burner is lighted, and in the instant construction, this can be readily determined by merely pulling the ash drawer D outwardly so that the person may clearly see the reflector R and determine, visually, whether or not the flame has been extinguished.

The burner is scientifically designed to burn slowly and under fully automatic conditions; however, the burner construction proper forms no part of the present invention which is directed to the general assembly of the shield, vent, and reflector.

The operation of the disposal unit is substantially as follows:

When the unit is set up and ready for operation, the ipe 22 is first connected to a suitable source of gas supply; the burner B is then ignited, and refuse and garbage (not shown) is then placed in the disposal chamber 1 through the door F, the flame from the burner extending through the openings l8 in the shield serving to dry and ignite the surrounding refuse, and the smoke and odors are drawn up the smoke flue It, and thence flowing through the pipe S directly to the outlet pipe and chimney (not shown).

The vent pipe extension is a safety measure; it eliminates any possibility of unburned gas collecting in the combustion chamber, and the reflector provides simple, practical means for determining, visually, whether or not the burner is lighted.

From the foregoing description, it will be obvious that I have perfected a very simple, practical and inexpensive burner assembly for refuse burning units and the like,

What I claim is:

l. The combination in a refuse incinerator having a combustion chamber, grate, smoke flue, and an ash drawer opening and passage in said refuse incinerator, a horizontally disposed support pipe extending into said combustion chamber, a standard T-fltting in said combustion chamber and formed with a leg, and upwardly and downwardly directed arms respectively with the support pipe connected to said leg, a vertically disposed, cylindrical shield of uniform diameter connected to the upwardly directed arm of said T-fltting, and perforated throughout, its length, a fuel line in said horizontal support pipe, a burner in the vertical shield and connected to the fuel line, a reflector mounted in the lower end of the downwardly directed arm of the T-fltting directly below said burner with its reflecting surface depending below the grate and disposed towards the ash drawer opening when in inclined position, and an angularly disposed pipe pivotally connected tg the upper end of the shield and communicating with the flue of the refuse incinerator." 7

2. The combination in a refuse incinerator having a combustion chamber, grate, smoke flue, and an ash drawer opening and passage in said refuse incinerator, a horizontally disposed pipe extending into the combustion chamber, a T-fitting mounted in the combustion chamber and formed with a horizontally directed leg and upwardly and downwardly directed arms respectively, said leg being connected to said pipe within said chamber, a vertically disposed, perforated shield connected to the upwardly directed arm of the fitting, a fuel line in saidhorizontally disposed pipe, a burner in the shield and connected to the fuel line, an angularly disposed pipe connected to the upper end of the shield and communicating with the smoke flue, an opening in said grate and into which the end of the downwardly directed arm of the T-fltting extends, a reflector hingedly mounted in the lower open end of the downwardly directed arm directly below said burner and adapted, when in inclined position, to extend into the ash drawer passage, with its reflecting surface disposed towards the ash drawer opening and through which the reflector may be observed.
